I have to agree with Michael, if the edge out of box was good then you just need to work on your sharpening technique. This is a very easy knife to sharpen, but you could lose a bit of height while learning. Agree as well that it could probably use some thinning. I thinned mine enough to make me happy, what makes you happy is up to you to decide. I would suggest sending it to a professional and let them thin it for you and also give you a good idea of what you should be shooting for in the future...again, as this knife is not very tall I may recommend experimenting with something older or less expensive but that is your decision. I've had personal experience with Jon's edges and they are awesome; I believe you could also send your knives to either Dave M or Korin and get equally excellent results.
